High Voltage Crynogenic Probe Compatible with Quantum Chambers
Radiant’s High Voltage Cryogenic Probe (HVCP) is compatible with Quantum Design PPMS© and DynaCool© Cryogenic Chambers. The fixture inserts into the Quantum Design system and connects to a Radiant Technologies’ Precision Non-linear Materials Tester to allow electrical testing of single crystal or bulk ceramic capacitors in the temperature and magnetic field environments created by the chamber. Electrical measurements up to 1,200 volts may be executed at stable temperatures down to 10 Kelvin with DC magnetic fields up to 9 Tesla without electrical breakdown of the internal helium atmosphere that cools the chamber. Measurements above 1,200 volts up to 4,000 volts may be executed without breakdown if the chamber is placed in High Vacuum mode at the sacrifice of temperature stability due to the lower density of the helium atmosphere.
